Parameter Description

<state>(num)

0	Audio path is in normal speech mode.
1	Audio path is in TTY/CTM mode.

Note

•Requirements for using TTY/CTM features:

-TTY/CTM functionality requires audio mode 5 or 6 with all audio parameters set to their factory default. To do so, first enter the AT^SNFS command to select audio mode 5, then use AT^SNFI and AT^SNFO to restore the default values. Alternatively, factory defaults of all audio parameters in audio modes 2 - 6 can easily be set with AT^SNFD.

-Depending on which audio interface the CTM device is connected to, you may need to select the correct settings with AT^SAIC.
